You must have missed my discussion of the PIN issue. Searching by PIN could be accomplished by "Search" then "1" to search by PIN.

I realize this is a small change to those who use PIN (they would have to type in one extra button press) but for those who use Artist, Genre, Source searches, it's a huge win. Making sure a remote button press "gets through" six times is difficult even with beeps, and in 2.0b3 there is a more noticable delay between when you hit search and when it switches to the next search view.
